    Does anybody happen to know the Clock Generator for the 6920-6141 so I can overclock my T8300 ? I have spent about two hours trying to figure it out and I just cant seem to find anything on it.

    Did you open up the notebook ? You should be able to see it by removing the upper casing of the notebook. It should be on the upper side of the motherboard. Check out this page to find out the physical appearance of clock generator chips.

    + Some Acer notebooks have their PLLs listed in txt files, accompanying the various BIOS updates. So check all of 'em on Acer's Euro Support Site.

    I would rather not have to dismantle my laptop but if it is the only way I guess I will. So I just go to Acer's Euro Support Site and check were ? Thanks for the info, I appreciate it. And also my T8300 has never been above 55C so what is the so called danger zone when I'm overclocking be ?

    Check all BIOS upgrades here for any txt files. You won't have to do alot of disassembly.
    You will actually be OCing the FSB, so apart from the CPU, it would also increase the frequency of the GPU and RAM as well.
    You will see an increase in temps when OCed and at full load, plus a few BSODs if the system goes unstable. It would also depend upon how much of the increased frequency the RAM and GPU would be able to handle. But first check out the PLL and see if its even supported by any software of not.

    by running a CPU at high temps constantly you are inviting failure!!


    that being said.....intel rates the T8300 to run at uptp 100c,, but if it gets above 90c you need to shut down and let it cool, IMO

    Thanks guys I will give it a go when I get a chance. One question Andy? So by raising the FSB on the CPU it raises the freq of GPU, does that mean that I should not overclock that by itself ? Once again, I appreciate all the info. I overclocked my Dell Inspirion 9300 about a year ago but only the GPU, so I have little experience overclocking the CPU.

    Yeah, either OC the GPU or the FSB.

    So let me get this straight here, if I overclock the CPU that would also overclock the memory frequency on the GPU, but what about the core clock and the shaders do they also overclock ? Thanks.

    I don't know how the overclocking goes on the GPU, but the increase is mainly in the frequency going to the CPU, GPU and RAM.

    did you find your clock generator chip?
    I believe I found mine but I don't recognize the manufacturer...
    The logo looks sth like B with a small H inside it, don't know. and the code is in three lines:
    GST5009
    LF
    0812S

    that's the only chip that looks similar to other clock generator chips

    Yeah, I found the same chip but could not find any info on it. I kind of stopped looking for right now because I getting really busy at college.

    hm, LAN, great, and that's the only similar chip I could find. I don't believe it's under the socket. Will open the laptop once more to see if there is a crystal somewhere near some chip, thnx for help.

    Which Socket ? I guess it should be on the upper side of the mobo, thats where PLL chips are surface-mounted in most notebooks.

    the newest cpuz says it's 478, I can't find the chip... What's the 'upper' part of the mobo?

    EDIT: oh, you mean under the keyboard? hm, I'm not sure I know how to remove it =)

    Yeah, the Santa Rosa platform only uses 478 pin CPUs.
    Yeah thats the upper part, keyboard side. :D
    I'll see if I can find some sort of disassembly guide. :)

    please do, cause I red some guide about unscrewing a couple of screws to release the keyboard but I don't see any screws that could have that function

    Hi marauder16, any luck on identifying the PLL?

    Thx

    I was kinda hoping that someone will do that for me :D because I went through the whole setfsb list of clock generators and not one worked, two of them showed some data, but wrong in both cases, others either returned some PLL error or crashed the system. that's why I'm not into opening my laptop and finding a chip which is on no-go list :(

    over clocking that system will cause more heat, which is the last thing you need considering the overheating issues that many NVIDIA GPUs are experiencing....

    atleast wait until setFSB supports your system... that's my advice.

    I'm not OCing, well at this moment I have no idea how I could. And I yet have to test how this GPU does in some newer games (temp wise), but the CPU is holding great, even with small ffts it doesn't go over 49-50C
